Two-stage turbocharger

  • 31-Mar-2008 06:52 EDT


In response to more stringent emissions requirements and increases in power and torque, BorgWarner Turbo & Emissions Systems has developed a regulated two-stage turbocharger, dubbed the R2S, for the North American diesel pickup truck market. The R2S consists of two differently sized turbochargers arranged in series. The smaller high-pressure turbocharger responds at low engine speeds while the larger low-pressure unit is responsible for providing boost at higher engine speeds. Compact dimensions make it possible to accommodate the entire R2S assembly in a space-saving manner, according to the company. In collaboration with International and Ford, the R2S system will be used on the Powerstroke engines in the F-Series of heavy-duty pickup trucks, as well as International’s MaxxForce engines in its light-duty trucks.
